1 Claim.

This invention relates to improvements in candy pails and other containers and its purpose isto provide improved means forsecuring the cover in place on the body of the pail or container. It

has been the practice in the manufacture and 'use of wooden containers and the like .to provide the container with a wooden cover secured thereto by nails or other fastening means. The principal object of the presentinvention is to provide an improved pail or other container comprising a vessel and a cover which are united by a metallic band or rim which is permanently attached to one of the container members before delivery to the customer or user and which is adapted to be bent into interlocking engagement with the other container member by the user, thereby avoiding the use of nails or other fastening devices. .A

further object of the invention is toprovide an improved pail or container comprising a vessel having an annular recess therein which is engaged by an inwardly extending part of an upwardly directed annular band adapted to receive a cover within it and to be bent over the upper portion of the cover to hold it in place. Another object is to provide an improved method of forming a container adapted for use as a candy pail, butter tub, or the like. Other objects relate to various features of construction and arrangement which will appear more fully hereinafter.

The nature of the invention will be understood from the following specification taken with the accompanying drawing, in which one embodiment is illustrated. In the drawing,

Fig. 1 shows a perspective view of a wooden pail embodying the improvements of the present invention; a I

Fig. 2 shows a detail vertical section through the upper edge of the pail and the adjacent portions of the cover and rim prior to bending the upper portion of the rim inwardly over the cover;

Fig. 3 is a detail section, similar to that of Fig. 2, taken on the line 33 of Fig.1, showing the relative arrangement of the parts after the upper portion of the rim has been bent inwardly 'to engage an annular recess in the upper surface of the cover, and g y Fig. 4 is a perspective view of a portion of the metallic rim or band in the form in which it is,

applied to the pail, as shown in Fig. 2, before placing the cover on the pail.

As illustrated in Fig. 1, the improved pail 10 comprises a plurality of upwardly extending wooden staves 11 which diverge upwardly to a slight extent and which are secured in assembled relation by means of a plurality of surrounding hoops 12 formed preferably of wire. Mounted on the pail 10 and seating on the upper ends of the. staves 11, is a wooden cover 13 of circular form which is secured in place by means of a metallic band or rim 14.

The pail 10, is provided near the upper end thereof with an annular undercut groove 15 formed in the outer sides of the staves 11 and providing a substantially horizontal shoulder .15. The sheet metal rim 14is constructedinitially to have the form shown in Fig. 4, where it is illustrated as comprising a cylindrical body portion -14'* having an inwardly extending flange. 14*.

along the lower edge thereof. The flange 14 -may be formed by passing the bandthrough suitable rollers to bend itinwardly and corru gateit transversely as shown at 14. The ends .of the band'14 are arranged to overlap each to permit'the band to be passed upwardly from below until its flange 14 snaps into engagement 1 with the recess 15 or, if preferred, the upper ends of the staves may be momentarily compressed to a sufiicient extent to permit the band 14 to. be passed downwardly from above until the flange 14 engages the recess 15. With either method, the upper ends of the staves, when released, return to their normal positions so that the flange 14 then has a definite interlocking engagement with the groove 15 and coacts withthe shoulder 15*. When the band- 14 has thus been applied to the'pail, the body portion 14 thereofextends upwardly above the pail to receive the wooden cover 13 which is preferably provided around the outer portion of the upper surface thereof with 1 band is then bent inwardly by a suitable instru- .ment to cause it to form an inwardly extending flange 14 which overlies the upper surface of the cover to hold the cover firmly in place. In the embodiment illustrated, the flange 14 coacts with the surface shoulder 13 which constitutes the bottom of the recess 13 The form of pail described above has the advantage that it may be manufactured with the band 14 applied thereto, as shown in Fig. 2, and

shipped to the user or consumer in nested relation, one within the other, while the covers are crated or tied in bundles and shipped separately. After the pails have been filled by the user with candy or some other commodity, the covers may be placed in position within the upwardly extending body portions 14 of the rims and then the upper portions of these rims may be bent over to form'fianges' 14, as shown in Fig.3.

Although one formbf the invention has been understood that the invention maybe embodied in various forms and constructed in various ways within'the scope of the appended claim; r

I claim: I V V The method of forming a container which consists in providing a wooden tub with an annular recess in its outer wall, then compressing the tub adjacent said recess and placing in position thereover a completed annular metallic band having an inwardly extending flange adapted to engage said recess 7 when the compressed portion of said vessel is subsequentlyreleased, then relieving the compression at said vessel, then placing a cover on said vessel within said band, and then turning the edge of said band inwardly over the upper edge of said cover.
